Feature request: Support session cookies with "Partitioned"

[nchaigne]

Third-party cookies will "soon" be phased out.
As seen in Firefox console for example:

Cookie "mojolicious" will soon be rejected because it is foreign and does not have the "Partitioned" attribute.

I would like Mojolicious to support "Partitioned" session cookies, so we can keep using session cookies with CORS.

Thank you for considering this.

Without a spec this seems unlikely to happen.

What do you mean ?
Do I need to specify how to do this ? or do we need an official spec from Mozilla / Google ?

Here are the specs: https://developer.mozilla.org/en-US/docs/Web/Privacy/Privacy_sandbox/Partitioned_cookies

@nchaigne e this is what I did:

                my $partitioned = $app->sessions->cookie_path;
                $partitioned =~ s/(?:; Partitioned)*$/; Partitioned/;
                $app->sessions->cookie_path($partitioned);

As the path parameter of cookie_path is not checked, it works.

Maybe this would be better?

                my $partitioned = $app->sessions->cookie_path;
                if (not $partitioned =~/; Partitioned(;|$)/) {
                    $app->sessions->cookie_path($partitioned . '; Partitioned');
                }

Gives current browser support, i'd be in favour of this feature.
